Shimano's Dura-Ace Di2 takes shifting to the next level. The Rear Wiring Kit connects to both the left and right shifters and Junction Box A (which displays battery power and allows manual adjusting). It also includes a battery mount, cable covers to route and hide the cables and a wire plug/unplug tool. The External Kit is meant to be run on the outside of the frame.
If you put in a lot of miles and/or sweat a lot, your shifter hoods probably need freshening up. Grab a pair of Shimano Di2 STI Lever Hoods to make your bike feel new again. - Fits Dura-Ace R9170 Di2 levers
